Class 12 NEET Physics Moving Charges and Magnetism

Distance between two parallel wires (x)=10cm=0.1m;
Current in each wire =I1=I2=10A and length of wire (l)=1m.
Force on the wire (F)=

µ0I1.I2×l

2πx

=

(4π×10−7)×10×10×1

2π×0.1

=2×10−4N
since the current is flowing in the same direction, therefore the force will be attractive.
